FOBJtCTi Aebastos - Substitution of Othtr Phodaalan Chrysotil* Grades -- , for Crds C and 0._____________________ la accordance with our pruals* at th* Mating of tho Operating foaltta* of tbo Coubinad Fa* Materials Board ysatarday, I an bspwr to glas you tbo following inforaation which you *111 no doubt slab to on to th* lllnlctry of Supply. C A 0/3 and CA G/A Although supplies of tb*o* fradaa appaar anpl* both for tba Onltad Stataa and tba United Kingdom, th* Mmr Production board arrentad last ball to hav* 10 aach of VFA/3 and VPA/4 sant to th* Onltad Stats* for experimental purposaa. Our anufacturors evaluated thaa* flbsr* and found than to h* talcy and not equivalent to th* C A G grabs* t and alatad that thoy *ould not saa than unoar any clrcunstanoaa. In raspact to HVL/3 and HVL/3U, our manufacturer* found that they **rt not entirely suitable for their usa. On* nanufacturar agreed to take V3% BV1/3 In place of C * G/3, but b* bad no ua* whatsoever for MVL/3XX. SJifiA. In th* spring of 1943 tbs Mar Production Board arrnngsd for a sample of VRA/2. This fiber was wary carefully axaalnad by tbs principal user of C A Q/7 in this country. Vary careful teat* ear* mad*, and It was found that the shrinkage as recalaad, after crushing and aftar opening, aas considerably la excess of C A G/2. The strd -hrlchaja, as w*U ** th* cor* roaing oasts, aas alaoet double, and tho tanaila strength ess about 60f loss. Tbo Per Production Board feel* that lh an aaerga-cy tb' flbsr night b* used as * substitute for C A G/2, but Its aalus under any test, whether labor*lory or production is decidedly less. As regards HVL/2, s nanufacUirsr in this country sndssaoursd to obtain s seaj-le for test. I quota fron a latter racalasd ty th* Bar Production Board fron this nanufacturar. As I Motioned to you whan at the nsating on Friday, Septasbar 2), Turner and IIsmall say produce eon* dVL/2 fron th* Havsloce Mias, which nay bo used in part as a substitute for C A G #2. They war* going to axpsrlasnt ith this fibre and ****** th* value of th* grads, and after th* production of BV1/2 bacons* standardised, th^ will, no doubt, sand us a seapl* so ws can try it in our sill. M* racalasd this inforaation fron Mr. Shepherd, of Turner A Bswell, during th* latter pert of August, and st Saptaob*, 71, recalled s latter fron thaa stating that supplies of IVL/2 are *likely ta asn> time, for aoao eonsldsrabl* tins, to suffer from surface ooataalaatlon. Me feel sura that you will net aleb to rooolvs u? aatarial ohleh Is not up to proper standard and representative of oontiansua supplies. Ms therefore propose to leave the order on ear bosks far oenpletlon as soon as the position at our Mines sakao this possible. Ibis being as, the ennalgnaaot *111 be twvoleag at the price ruling at data of shlpnant*. Ms shell, ns dewhi, receive additional iaforaation free Turner and Hsaoll as the year prograasas, and sill keep you advlsod as so.- mm mm iuai lu M th* # *e*ta i lira is. ?*e- preAsrtleo.* Iba far Production Board stataa that until Turner sad Saaall _*o fit ts sand thasa aanplas, test* cannot ba parforuad, but that a* soon a* th* sa^ilas of HVl/2 ar* rubai Had they *111 naka certain that thasa are thoroughly tested users ts the Onltad Stales. y~~ytr`yk^|.,Tvtutchsff.
